  • Patent number: 10350408
    Abstract: A catheter inner assembly includes a receptacle with an interior contour configured to mate with a head and neck contour of a holding member of an implantable medical device; and a laterally facing opening of the receptacle has a profile matching a longitudinal profile of the head and neck. Thus, the opening allows only a properly oriented passage of the holding member therethrough, the passage being without deformation of holding member or opening. The inner assembly further includes a lock and release member useful for securing the device to the catheter, when the holding member has been passed through the receptacle's opening to mate with the receptacle's interior contour. The lock and release member may include an arcuate sidewall moveable between a first location, at which the sidewall overlays the laterally facing opening, and a second location, at which the sidewall is located proximal to the opening.

  • Patent number: 10278768
    Abstract: An end effector assembly for an electrosurgical device includes first and second jaw members movable between spaced-apart and approximated positions. The jaw members define opposed tissue-contacting surfaces that cooperate to define a tissue grasping area within which tissue is grasped when the jaw members are moved to the approximated position. At least one of the jaw members includes an interior electrode and at least one of the jaw members includes first and second exterior electrodes. The interior and exterior electrodes are configured to conduct energy through tissue grasped within the tissue grasping area to seal tissue. The interior electrodes are disposed interiorly of outer bounds of the tissue grasping area, while the exterior electrodes are disposed exteriorly. As a result, upon conduction of energy through tissue grasped within the tissue grasping area, tissue disposed adjacent the exterior electrodes is boiled before boiling of tissue disposed adjacent the interior electrodes.

  • Patent number: 9931111
    Abstract: A suturing instrument includes a suturing head that is coupled to the shaft of an elongate body member of the instrument by a connector member which may be biased in either a linear orientation along the longitudinal axis of the shaft or any one of a variety of non-linear orientations with respect to the shaft's longitudinal axis. The connector member can comprise a resilient material such that an external force may be applied to the suturing head and move the suturing head from a biased orientation (e.g., linear) to an unbiased orientation (e.g., non-linear). Once the external force is removed, the resiliency of the connector member allows the suturing head to return from the unbiased orientation to the biased orientation. Therefore, a user may adjust the shape of the instrument by applying or removing an external force on the suturing head.

The outer component includes an internal boss that reduces its internal diameter, and the cannula includes fingers that extend distally. When the needle is inserted for biopsy, tissue enters the outer component and cannula. Moving the cannula forward causes the fingers to engage a surface of the internal boss, resulting in the fingers curving into the tissue. The fingers pinch the tissue while reducing or eliminating compression of the sample to provide an easier removal of the tissue from adjacent tissue, as well as providing a block or backstop keeping the tissue within the needle. Gaps are provided between the fingers to further reduce damage to the tissue sample.

    Abstract: A latch mechanism for a surgical instrument includes a lever moveable from an initial position to an actuated position for moving an end effector assembly from a first to a second state. A pin extends from the lever. A cantilever spring is operably engaged to the housing of the instrument. A pin track member is operably engaged to the cantilever spring at a free end thereof. The pin track member is configured to permit translation of the pin therealong between a first position corresponding to the initial position of the lever and a second position corresponding to the actuated position of the lever. The pin is configured to translate from the first to the second position along a first path and from the second position back to the first position along a second path and is configured to be releasably retained in the second position.

  • Patent number: 9017372
    Abstract: A forceps includes first and second shafts, each having a jaw member disposed at a distal end thereof. At least one jaw member is moveable from an open to a closed position for grasping tissue therebetween. At least one jaw member is configured for reciprocation of a blade therethrough. A trigger assembly includes a trigger and at least one linkage coupled to the trigger and to the blade such that rotation of the trigger translates the blade between the retracted and the extended position. An interference member moveable between a locked position and an unlocked position is also provided. The interference member is configured to engage the linkage(s) when in the locked position to inhibit translation of the blade from the retracted to the extended position.

  • Publication number: 20150112382
    Abstract: The invention relates to a completely mechanical laparoscopic surgical instrument which can be disposed of after a single use or which can be sterilised and re-used more than once. The instrument essentially comprises: a gripping zone provided with two gripping elements (2, 3) hinged to one another by means of a pivot shaft (4), a working tool (30) provided with two jaws hinged to one another by means of a pivot shaft, and an actuation mechanism that can transmit movement from the gripping zone to the working tool (30). According to the invention, the tool can adopt multiple positions and/or orientations during its use with the assistance of substantially annular bodies that are coupled to connecting rods associated with the gripping elements.

  • Patent number: 9011468
    Abstract: The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

  • Patent number: 8998912
    Abstract: A patella drill guide includes a base with a flat patella bone-facing surface, a drill guide bore extending through the base, a cantilever spring member and a bone-gripping member. The cantilever spring member biases the bone-gripping member and the flat patella bone-facing surface toward each other. Flexing the cantilever spring member moves the bone-gripping member away from the flat patella bone-facing surface so that the drill guide can be placed on the patella. When the cantilever spring member is released, the patella is clamped between the bone-gripping member and the flat patella bone-facing surface. The drill guide may have sizing indicia and may be part of a kit including trial components to be mounted to the drill guide.

  • Patent number: 8968357
    Abstract: A surgical instrument includes a housing supporting first and second actuators, an elongated shaft extending distally from the housing, and an end effector supported by a distal portion of the elongated shaft. A tensile member extending through the elongated shaft is coupled to the first actuator and the end effector such that first actuator may be manipulated to induce motion of the end effector. A locking mechanism associated with the tensile member selectively impedes motion of the end effector. The locking mechanism includes a collet disposed about the tensile member and a collet clamp for receiving the collet. Receipt of the collet into the collet clamp induces radial compression of the collet to impede the motion of the tensile member therethrough. An actuation member extending through the elongated shaft induces insertion and withdrawal of the collet from the collet clamp.
